I would like to ask you one thing: what is the difference between audit risk and risk of material misstatement? Some questions aka audit risks whereas others require to find risk of material misstatement.
This is definitely covered in the notes – if you search “audit risk model” you will find a good summary. Essentially AR = IR x CR x DR where IR x CR = RoMM
Therefore the difference between being asked for AR and RoMM is that AR requires you to consider DR also.
